To all whom it may concern: Silica u 18.63 parts. Be it known that we, JACOB A. SCHMI'I'I" Gypsum 29.32

and CHARLES R. BELL, citizens of the United Glycerin 1.12

States, residing at Chicago, in the county of Chlorid of zinc.. .24

Cook and State of Illinois, have invented W'ater 18.23

certain new and useful Im rovements in Composition of Matter, ()T WhlCh the following is a specification.

Our invention consists in the provision of a composition of matter which has the property of absorbing large quantities of Water and having such an aflinity for water that the surrounding atmos here maybe maintained thereby in a uni ormly humid condition for a protracted period of time.

.Our invention is especially applicable for the production of humidifiers *foruse to maintain the atmosphere in a moist or humid condition.

The composition consists of the following ingredients combined insubstantially the proportions stated Calcium oxid .92 parts. Silica 18.63 Barium sulfate 3.37 Chlorid of zinc l l .24 Glycerin 1.12 Aluminum .60 Ferric oxid .84 Gypsum l 29.32 Calcium carbonate 9.37 Cotton floss 2.63 Clay 3.60 Magnesium .78 Coloring matter .36 Waterz; 28.22

Many of the ingredients are found in their natural state in the clay andsilica, and, therefore, reduced to its sim lest state,. the formula is substantially as fo ows:

Clay"; 29.83,parts. I Vegetable fiber 2.63

These ingredients are to bemixed thoroughly by agitation and-kneading and then.

molded into suitable forms.

The clay andsilica form the main orous body. The gypsum is the chemical inder and hardener andforms a considerable-portion of the porous body after it has become set. The chlorid of zinc and glycerin have In use, the bod is immersed in water,

considerable afiinity for Water and tend to taken up by infiltration. Our composition may be molded into convenient form and used as a humidifier in receptacles oontain-. ing cigars and the like for maintaining the contents uniformly damp.

What we claim is:

The herein described composition of mat ter consistin of'clay, silica, a fibrous mechamcal bin er,1 a chemical binder, glycerin,

and chlorid of zinc, substantially as and for the purpose specified. p In testimony whereof we hereunto set our hands. 1 p
